Afternoon all.
Can anyone advise me on this?
I have Bridgestone's that are about to be replaced this week. Two of the tyres have traditional 4 digit DOT codes to denote the week / year of manufacture.
Two others (1 front and 1 rear) don't have any 4 digit codes that I can pair back to a manufacturing date. There really doesn't seem to be anything other than the codes in the images below. I've googled it, looked on the Bridgestone web site and can't work it out.
I have the receipt from Porsche East London that these two tyres were fitted in 2017 - but I want to be able to verify the date.
Any thoughts?
